Inaccurate performance data for BOB fighters in COD comparing to RL data

Again, there's E-7 (601Aa) and E-7/N (601N).

Now there was 32 E-7 in the end of August, I agree not very significant, according to the paper they entered service and went on operation just a few days earlier. I think the Ib analogy doesn't stands, it was a single Squadron, and a completely unsuccessful one. Personally I wouldn't mind having it, I just consider it a compete waste of time of developer resources to model a completely useless plane (because of insta-jams). I think Galland's own Gruppe flew the E-4/N and I would bet a leg on it they ranked up quite score during BoB.

Probably because their production just started (none listed as produced as of end of June 1940 yet, so production just started in July or early August). Following that however a total of 186 were produced until the end of October (these would be certainly with 601Aa, again the priority of 601N distribution to 109s did not come into effect until November), so I would expect that in September-October there were fair numbers of them around. Say, 80-90 or more? Pretty much like Mk IIs (was it 5 or seven operational Sqns?).

In any case, I do not see why a Spitfire II, which saw service in similiar numbers and time (1-2 Sqns in August and best, and about half a dozen Sqns by the end of the Battle, is a more justified as an aircraft model than E-4/Ns or E-7s, which at the minimum equipped 2 Gruppen (Six Squadrons), by late August, and probably more in the automn.

The second strenght return list from January only list E-7/N, so its additional to 'normal' E-7.

The absolutely correct historical way would be to model separately an E-4/N (601N) and an E-7 (early 601Aa variant), both were there but in small numbers, say about a hundred or so combined by the late Battle.

What I think would actually make sense and fit into the sim nicely is to model an E-7/N straight away. This is sort of a hybrid but can represent the number of E-4/N and E-7 participating in the battle economically with modelling resources, moreover the E-7/N can be re-usable for 1941 scenarios (North Africa, Malta, Moscow, France 1941), since in 1941 it was the main type and the only 109E type remaning in production, with several hundred produced (ie. all late E-7 seems to have been E-7/N). Its probably being done for the Moscow sim anyway.. and would require little more than a minor change in the external model (pointed spinner, spark plug cooling holes on the cowl, drop tank rack) and FM of existing E-4.

E-4/Ns also listed in January at 54 pcs, one Gruppe of JG26 used them quite early, that might be cca 40 aircraft in the Summer already (makes sense). I guess Perez's aircraft was part of this Gruppe. It seems that 100 octane fuel and 601N engines were more relevant for Bf 110s Squadrons in the sim. In the actual Battle of Britain, these subtypes were present at rather marginal numbers - at 31.8.1940 we've got 871 Bf 109s in service, let's say some 1é or less % were fighters with DB 601N.

Same with droptanks coming in November - this is very important for next stage of the war (the Blitz as the British call it).

Absolutely agree. Its important for the 110s, since about half of them had the 601N, and its a real performance boost for them, being much faster. A BoB sim without 110/Ns is pretty much like a BoB sim without Hurricanes, given their historical force ratios... or +12 boosted variants for that matter.
